Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is control principle block diagram of the present utility model；
Flow chart when Fig. 3 is the utility model actual motion.
Embodiment
As shown in Fig. 1 and Fig. 2, the leaf storing cabinet quantitative discharging control system on a kind of tobacco processing line, including bearing wheels 2,
Multiple tested devices, proximity switch 5 and PLC 6, bearing wheels 2 are arranged on the rotating shaft 4 of the tail band motor of leaf storing cabinet 1
One end, multiple tested devices are uniformly circumferentially positioned in the cylindrical side wall of bearing wheels 2, the shapes and sizes of multiple tested devices
All same, proximity switch 5 is arranged in the side wall of leaf storing cabinet 1 and test side and the cylindrical side wall of bearing wheels 2 is just corresponding；It is described to connect
The model of nearly switch 5 is preferably precision height, and installation is with modulating simple ML4-8-KSU-2325, the induced signal of proximity switch 5
Output end is connected with the induced signal input of PLC 6, when tested device turns to the test side of proximity switch 5,
Proximity switch 5 can send induced signal to PLC 6；The control signal output of PLC 6 and the bottom on leaf storing cabinet 1
Control signal input with motor is connected for the operating for controlling tail band motor, PLC 6 also with for
The PLC control system of the control feed end inlet amount of leaf storing cabinet 1 communicates to connect and then can obtain the gross weight that leaf storing cabinet 1 enters cabinet material
Amount.
The multiple tested device is bolt 3, and bolt 3 is preferably four, and four are provided with the cylindrical side wall of bearing wheels 2
The individual screwed hole being engaged respectively with four bolts 3；Four bolts 3 screw be fixed in the cylindrical side wall of bearing wheels 2 and
Symmetrical two-by-two, the top of four bolts 3 is equal with the distance between the cylindrical side wall of bearing wheels 2, using bolt 3 as tested dress
Put, it is not only cheap, and the distance between the top of bolt 3 and cylindrical side wall of bearing wheels 2 can be adjusted, and facilitate proximity switch
When sensing insensitive, adjusting proximity switchs the distance between 5 test side and top of bolt 3 after 5 fixations.
The system forms PLC 6, tail band motor and proximity switch 5 by being programmed in PLC 6
PID closed-loop control systems, because the velocity of rotation of bearing wheels 2 can directly reflect tail band motor running speed, by connecing
Nearly switch 5 can substantially reflect tail band motor to obtain the number that the bolt being arranged in 2 cylindrical side wall of bearing wheels passes through
The speed of running speed, and then control the running speed of tail band motor to realize quantitative discharging control by PLC 6.
Mainly include default stage and actual motion stage when the system is run, mainly include following step in the default stage
Suddenly：

Enter cabinet material gross weight to leaf storing cabinet 1.
（2）Marked in the tail band of leaf storing cabinet 1, control tail band motor to simulate manually according to the discharging flow of setting
Tail band discharges, the impulse generator using proximity switch 5 as the sensing tail band of leaf storing cabinet 1 operation, whenever bolt 3 is approximately rotated to out
When closing 5 test side, proximity switch 5 sends an induced signal and counted to PLC 6 as pulsatile once, PLC
6 calculate tail band senses number that bolt 3 turns over, i.e. pulse sum from discharging is started to proximity switch 5 when terminating to discharge.
（3）Cabinet material gross weight is entered according to leaf storing cabinet 1, with reference to pulse sum, calculates the arteries and veins in the unit interval of setting
Number is rushed, PLC 6 is set.
As shown in figure 3, the actual motion stage mainly comprises the following steps:
（1）During actual motion, start tail band motor and carry out actual discharging, during actually discharging, leaf storing cabinet 1 starts
PLC timing starts during discharging, the time out when discharging of leaf storing cabinet 1 stops during discharging；Continue the then timing that discharges, when
Leaf storing cabinet 1 stops timing after the completion of discharging.
（2）In timing course, PLC 6 calculates the actual pulse number in a unit interval every the t seconds, and t≤
3s, the actual pulse number in the unit interval and the umber of pulse in the unit interval of setting are contrasted, pass through pid control circuit
The rotating speed of tail band motor is adjusted, the transporting velocity of the tail band of leaf storing cabinet 1 is controlled, realizes reactor effluent stream of the leaf storing cabinet 1 according to setting
Measure material.
In summary, the system is by carrying out simple upgrading on existing leaf storing cabinet 1, making PLC 6, bottom
PID closed-loop control systems are formed with motor and proximity switch 5 to control the speed of service of tail band motor, and then are realized
The quantitative discharging control of leaf storing cabinet 1, whole escalation process need not change the outfit to the internal mechanical component of leaf storing cabinet 1, install
Simple with debugging, cost is cheap, is adapted to use in tobacco business large-scale promotion.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should manage
